Objectives：The new portable laryngeal stroboscopic torch is developed to complement one by stable synchronization, high illumination and wireless on screen display of Hz, dB, Mode. Materials and Methods：The two-lens system is created to enhance the condensing effect of LED, with a comparison of non-lens system and other light sources. With the results of development and evaluation, such information as Hz, dB, mode were superimposed on screen by the software without any superimposed captureboard. Results：1. Simulation of the maximal central illuminance with no-lens and two-lens systems using the LightToolsⓇ software shows the 15 times higher results of 4,910±944 Klux and 330±65 Klux respectively. 2. The maximal central illuminance of the two-lens system light source is compared with those of S company’s xenon 300 W (USA), S company’s xenon 300 W (Germany), C company’s halogen 150W(USA), and domestic M company’s halogen 150W. While the maximum central illuminance of the two-lens system light source is lower than those of S company’s xenon 300 W (USA) and S company’s xenon 300 W (Germany) light sources, but it is a little higher against light sources of C company’s halogen 150 W (USA), and domestic M company’s halogen 150 W. 3. The wireless telecommunicating protocol of 433 MHz make the on-screen display effectively. Conclusions：Developed portable laryngeal stroboscopic torch can be stably synchronized only by voice signal, with high illumination. It can also superimpose monitor information of voice signal such as Hz, dB, mode on a wireless basis.
